Armstrong Fluid Technology announced that its popular Design Envelope (DE) 4380 Vertical In-Line pumps are now also available in Stainless Steel. Ideal for domestic water and light industrial use, these pumps are certified for safe drinking water systems to the NSF-61 and NSF-372 standards.
The DE 4380 Stainless Steel Pumps can also be used in many light industry petroleum and chemical applications and offer advanced Design Envelope solutions which include DE Permanent Magnet (DEPM) motors, Parallel Sensorless Pump Control, built-in Wi-Fi connectivity, touchscreen control, and optional Pump Manager capability.
The Stainless Steel DE pumps offer:
- Up to 70% energy savings
- Permanent magnet motors
- Built-in Parallel Sensorless control
- BMS connectivity
- Advanced hydraulic design with industry-leading ?ow efficiency
- Control algorithms that review operations constantly and adjust output
- Smaller footprint and lower total weight than traditional units
The DE 4380 is available in six models ranging from 1 to 2 hp, supporting performance levels from 10 to 1,185 gpm flow, and 10 to 75 ft head. It is designed for continuous low-pressure circulation, including water circulation, cooling towers, fountains, irrigation, spraying systems, condensate return, filtration, and many other applications.
